An electron and a proton are moving with the same kinetic energy along the same direction, When they pass through a uniform magnetic field perpendicular to the direction of their motion, they describe circular path of the same radius. Is this statement true or false?

Explanation

`r=sqrt((2km))/(Bq)=rpropsqrtm` `(k,q` and `B` are same)
`the path will be a helix. Path is circle when it enters normal to the magnetic field.
